HARRY C. GAMMETER, OF BRATENAHL, OHIO, ASSIGNOR TO THE AMERICAN MULTI- GRAJPH COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF OHIO.

DUPLICATING MAGHINE Specification of Letters Patent. I

Application filed January 3, 1910. Serial No. 535,962.

ToaZZ whom it may concern:

Be it known that I, HARRYC. GAMMETER, a citizen of the United States, residing at Bratenahl, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Duplicating- Machines, of Which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

One of the objects of this invention is to provide a simple and elficient duplicating machine having the capacity of rapidly printing matter with a portion of the form successivelychanged.

My invention is especially designed for printing circular letters, wherein the body of the letter is the same for successive impressions and the address is changed.

Another object of the invention is to provide such mechanism that an impression may be made from the changeable part of the form without printing the balance of the form. This is of especial value in printing the addresses on envelope to match the addressed letter.

Another object of the invention is to endow the mechanism With a capacity for printing the letter and the envelop alternately and delivering the same adjacent to each other.

Another object of theinvention isto provide for printing both .circ'ular letters and the envelope in. imitation oftypewriting, the

impression being made by .type of typewriter pattern through an ink-carrying :t'abl'ic.

Another object is to provide .the .meehanism in such form that-the Qhangefrom one another. may be made quiekly and easily. V

Among other obgeets may he mentione provisions for effecti ely feeding and nontrolling the ribbon; for allow ng the removal of the,type dorm-as a whole sand. in general, for rendering the. construction efficient.

The inventiO a V be mosteonveniently (summarized as consisting of the combine tions of cooperating partsby which Inccomplish the. above-mentioned ob ects or any of them, as set out in the Claims.

In the embodiment shown, my machine is W ates for therot teble yp holder m te e ween h m.

Th3 Wpeholder comprises a drum-like member mounted on .a shaft 13 journaled .inthe end plates, and provided with a suit able driving mechanism, as the crank 14;.

rim portion ternal webs 22 rigid with the rim portion, and a sheet metal hook 23 which is hinged to thewebs by a rod 24 mounted 'therein,

and at its other end 'is rolled to spring around and engage the shaft 13. This hook bybeing of spring metal, and being normally bent intermediately, as shown in Fig. 6,, has the capacity to spring around the shaft 13 and at the same time retain a firm hold thereon. When the spring hook is in the position shown the segment is firmly held with its rim seating on the spiders'lfi and 17. In this'position thewebs substantially abut suitable bars 25 connecting the spiders. The drum opposite the segment. is open, so that there is convenient access to the hook 23 for removal and replacement of the segment.

indicates a suitableroller platen mount ed parallel with the printing drum and having a soft cylindrical surface adapted to cooperate with the; type on the drum. As shown more particularly in Fig. 12,thissoft surface is placed about a metal shell 31 which has hardened bushings .32 and 33 journaled on a shaft 34. This shaft has reduced I eccentrically-placed extensions 35 and 36 lever 38 provides manual means I also provide auto- 'cally mounted and may be adjusted towar which is adapted to nection from this gear to which are journaled in the end frame members 11 and 12' The platen is thus eccentri-' or from the printing drum by turning the shaft. This adjustment. may be made by hand, whenever desired, by means of an arm 38 on the extension 36 which is adapted to swing between stops 39 and 40 on an areshaped bar 41 mounted between guides on the end plate 12 andclamped by a set screw 42. The arm 38 may carry a screw 43 or other device adapted to occupy a .44 in the arcual bar,

to lock thevpiiten 1n ile the for raising 48 in the end of the platen.

To ink the type whereby it may print upon paper-drawn between it and the platen, I provide an inking ribbon 50, one end 0 which is mounted on a spool 51 journaled in the spiders 16and 17. The other end of the ribbon is mounted on a spool 52 which i carried by the frame and connectedwith .4. spring barrel. Thus, as shown in F lgs. 1

18 a plurality of arcual in-, and 3, the spool 52 and 63 mounted' depression engaging slots of the machine on the end of short arbors 57 brackets 53 and 54.. A spiral spring 60 is provided within a casing 55, loose on the arbor 57 and connected by a pin spool. This spring connects at one end with the casing and at the other with the arbor 57. This arbor has a regulated brake en-" gagement with the bracket 53, by meansof a spring washer 58 between the bracket and nuts 59 on the shaft. The operation of this spring connection is. to allow the ribbon to be pulled off of the spring barrel and wrapped around thedrum during printing movement, and on the reverse movement to wind in the ribbon on the barrel, this-action being accordingly similar to that of a shade roller. I

I prefer tatable' skeleton frame for periodically feeding the ribbon, as by giving the spool 51 a partial rotation for each rotation in the proper direction of the printing drum. Such feeding mechanism, for example, may be a ratchet mechanism herein in Fig. 4. Brieily, the parts there shown comprise a reciprocating bar 151 d mounted on the end spider 17 and connect eccentric surrounding ing with a stationary the shaft 13, whereby inor out as the drum turns; pivotally mounted on the bar; a

the bar is reciprocated a plate 152 pair of a suitable stationary to .provide mechanism on the re is journaled at the front 62 with the flange of the made in accordance with my Patent No. 997,287 and illustrated pawls 153 and 157 pivotally mounted on the plate; a spring 154 acting to force the pawl noses outwardly; spring constrained lips 160 to limit the outward movement; and a spring detent comprising a roller 155 and a spring 156 tending to hold the plate 152 in either of two extreme positions. When'in the position shown in Fig. 4, the pawl 157 is in position to engage the ratchet 158 of the spool 51. The other pawl isidle in the position, shown. When the spool 52. is mounted on the is always on the spool 51.

As the gradual feeding of the ribbon onto the spool 51 increases the spring tension in the spring barrel, the spring washer 58 allows slippageof the shaft 57, so that the tension on the ribbon is maintained approximately constant. This tension may be regulated, as required, by turning the shaft 57 by its crank-i151.

The. spool 52 is readily removable, by pressing it toward the right (Fig. 1) to release its connection with the casing 55, and then tipping it and removing it from the pin 63. The spring 64 allows this move- -ment. -When removed from the mounting described, thespool may be mounted in the drum parallel spring barrel, the feeding I 15?) causes the plate memes in my Patents Nos. 997,287. and Reissue 12,622. When both spools are mounted in the drum, as shown in Fig. l, the tautness' of the ribbon when entirely wound on the spool 51 (by reason of anchoring the pawl 152 to automatically swing to bring the pawl 153 into position to cooperate with the ratchet 159 of the spool 52, thus the ribbon automatically reverses itself. I As heretofore stated, my machine operates by giving substantially a rotation in one direction to effect and address, direction to velops.

Figs. 1, 3 and 7 show the position of the parts as the printing of the letter is about to begin. The sheet of paper to be printed is placed on the table against suitable stopfingers 66, (Fig. 6) and then as the crank is rotated in the left-hand direction the spool 51 travels rearwardly and upwardly and the type form-swings clown- Wardly on the front end of the machine, and at the proper time the paper is released andf-ed rearwardly by feed rollers 67 and 68. In such movement the paper passes be tween the drum and platen. Now, this lefthand movement of the printing drum-rotates the platen by means of the gears 4i?) and 46, and, by means of a frictional connector between the platen and its shaft, this rotation of the platen in the right-hand direction au tomatically turns up the shaft 34 so as to elevate the platen and bring it into print ing position. The frictional device in the form'shown consists of a sinusoidal spring 70 placed within the platen shell and bearing on the inner surface of the shell and on the-shaft 34:. Suitable cam and lever mechathe printing of the'body and a rotation in the opposite effect the printing of the ennism (not shown) operate at the proper .point in the rotation of Patent No. 846,992. Accordingly, whenthe drum is given this left-hand rotation the platen is automatically turned up into active position, and the paper, with the ribbon above it, passes between the platen surface and the type on the drum and is thereby impressed. In such movement the sheet passes between the ejecting device consisting of a rubber roll 72 and surmounting steel rolls 7 3 and is thereby-delivered. Both rolls are slidably mounted on shafts 172 and l7%$, respec'tively, by feathers on the rolls engaging grooves in the shaft, whereby the rolls may be adjusted for "different widths of paper. The shafts are ge'ared tcgetherby meshing gears 174 and 175, the latter of which meshes with an idler 118, which, in turn, meshes on a radial axis,

with the drum gear 45. Now, as soon as the crank has made substantially a rotation in the left-hand direction, resulting in the printing of the letter with its body and address and the delivery of the same, as described, the crank is given a rotation in the right-hand direction to print the envelop by the same address form through the same ink ing ribbon. The mechanism by which this operation. is eii'ectedwill now be described.

In the embodiment shown, inounted on the rear edge of the plates 11 and 12 are brackets 81 and 82 in which is rotatably mounted the shaft 83 carrying a roller 84 on which is mounted a soft segmental platen 85 for printing the envelop. The roller 84 may be a sheet metal shell, and heads 86 and 87, or other construction as desired. The mounting in the brackets 81 and 82 is adjustable, by reason of the ends of the shaft 83 extending into eccentrically placed. bores in bushings 88 and 89. These bushings have knurled heads by which they may be turned and are clamped by suitable set screws, as 90 and 91. "The arcual extent of the surface of the platen 85, or the position of this platen on its roller, is such that the platen is adapted to co-act with the address portion only of the form.

To cause the envelop platen 85 to revolve ccactiugly with the address form, but to be idle while the rest of the drum is passing the platen, I provide the following mechanism: Mounted on, the hub of the bracket 82, or in other suitable manner. is a gear 92 which meshes with the gear as and is thus rotated whenever the drum is rotated. Pivotally mounted within a slot in this gear, is an arc-sl1aped dog 93 (Figs. 5, 9 and 10). This dog has apair of oppositely projecting lugs 94. and 95. The lug 94c occupies an elongated slot 96 in the head 86 of the platen roller. The lug projects beyond the outer face of the gear in position to engage a stationary cam projec tion 97 carried by the bracket 82. A spring 98 carried by-the gear 92 and acting on the dog tends to keep-it with the lug 94 in the slot 96.

The result of the operation of the above. described mechanism ing drum is rotated in the left-hand direction to print the letter, the platen roller 84 rotates correspondingly, with the platen85 in idle position, because it is passing the drum when the open space thereof is at the rear. When such rotation brings segment 85 intoan upwardly extending position, the lug 95 engages the cam 97 which swings the dog 93 to withdraw the lug 94 from the slot 96. The'cam holds the lug 94 withdrawn until the rotation has carried the lug 9% beyond the slot 95, whereupon the continued rotation of the ear 92 carries the lugaround on the end or the platen headis that when the printthe platen 1 86, a friction brake (provided by a split- Washer 99, or other suitable means) holding the platen in stationary position, Accordingly, this printing rotation of the drum gives no effective operation to the envelop platen, but simply turns it to proper position and then leaves itthere during the rest of the rotation. The position of the parts at the end of the left-hand rotation is shown in the diagram, Fig-8. Now, after the reverse rotation has begun, (thatis, the-right hand rotation of the drum) the dog 93 springs back into the slot 96-and drives the platen roller so that the segmental platen 85 5- swings downwardly toward the front just as the address form is swinging downwardly toward the rear, and the two cooperate to print an envelop placed between them.-

I provide a support for the envelop while it beingprinted, consisting of a pair of sta ionary rods 105 and 106 carried by the y brackets 81 and 82 and a pair of slidable bars 107 and 108' mo'untedon these rods;

- The bar 107 preferably hasan edge guide109. The bars may beslid along the rods to any desired position. Each bar is provided with an adjustable ,foot stop consisting of the lip 110 clamped to the bar by a suitable set screw 111 which is'slidablein the up-and down slot. 112 in the bar. Preferably after theletter has been printed and before the reverse rotation begins (or in the. vicinity of this momentary pause) the envelop is placed on the guides 107 and 108 against 5 the feet 110, with its fiap downward'andl toward the rear; that is, the'envelop is upside down and facing the printing .drum.

Now, on continued .right-handrotatipn of thedrum, thea'ddre'ss form swings onto the" I 0- face of'the envelop and the segmental platen 85 at the 'same time comes onto the rear of the envelop, so that the envelop is gripped betw en them, and as the address type and.

platen roll on each" other, the lower edge of the envelop buckles free from the, foot stops '110 and is l-fed by the address type and plated, so that the address is printedon the envelop by a rolling impression. Furthermore, the envelop is automaticall'yffed downwardly by such movement, so that at the completion. of this rolling'coaction the printed envelop drops onto the ejected prints ed letter to which it corresponds.- At the beginning of this right hand rotation of 55. the drum the main platen 30 is automaticallythrown to idleposition by its frictional grip (on the eccentric shaft, and remains in this position throughout. the rotation. Q

The position of-the ribbon and the main e0 platen and envelop platen at the beginnin of the envelop printing movement, as state is illustrated by the diagram in fFig. 8. After the envelop has, been printed, the

movement'is continued for substantially the 66 remainder of a complete rotation-, and-thus' is a segmental sheet of metal having slots ;l21 extending from one end we toward the' while the clip 124 is slidable lengthwise of' '124'has a-pair of. tongues 126 which are plate, removing it, placing a new plate; and

return the parts to initial positio that isthe position shown in Fig. 1. In this position the address plate 120 may be removed and a new plate substituted, as will now be described. I

The removable address plate 120 and the means for securing it in place are shown, described and. claimed in .my Patent'No. 1,088,410. Briefly, the plate 120, as shown,

other en-d,.whichslots leave between them tines adapted to alinewith the heads of rails 19. when the plate occupies a suitable ,recess'122 in the drum. The address plategg when in place rests on web portions of the rails at the recess. 122, and its surface is flushwith the outer'surface of the drum. These rail webs support the plate between, 1 consecutive lines of type. Theselines' of 5 type areindicated at 132, in Fig. 1. They consist. of individual typergrooved on their oppositesides and aregidentical with the main. rintin'g type,uand"held inplace by suitab e elastic plugs 1533. In position the plate is held by a suitable clip-123 which overhangs one edge. and a slidabl'e clip 124 overhanging the other.' Each of these clips is held in place by suitable ribs, (not shown) occupying the under-out channels between consecutive rails and secured to the clips by rivets, shown in Fi .:1. The clip 123 preferably engages the rum with sufiicient friction to render ,it normally immovable,

the drum, with more or less freedom, the clip preferably having a roughened or corrugated upper surfaceto enable it to be easily moved by the operators fingers. The clip adapted to overlap the edges of the plate 120, or to aline with ,suitablenotch'es in that edge, such alining taking place when the clip abuts astop 129. A suitable spring 130 tends toelevate theedge of the plate adjacent to the clip 124. Now, when it is desired to "replace the plate byjone carr ing a new address(which is preferably one in the pause between right hand and lefthand rotations the"operator slides the clip 124 to the-1e "t, until the tongues 126 aline with the'notches 127 The spring 130-thereupon elevates the free edge of the address .plate and the same is pickedjout' by the operators fingers and a newplatetucked under the clip 123,"pressed down against,the spring and locked invplace by the clip 124, being slid to theright o'vefthe' top of the plate. This operation of unlocking the locking it, may be erformed by the operator .with' one zhandf'with great rapidity. When the new late is in law the machine iis operate asbefore, rst b a left-' hand'rotat'ion to print the-body ai iaddress 130 on the letter, deliver the letter and bring platen .30 may be held permanently and .the drum a ..removable address with the address 'thejnachine may and both the body and ad the address above the envelop platen, then by a right-mild rotation to print the en. velop, and return the type form to uncovered position for installing a new address plate.

shown in the drawings, the .salutation' is carried by the printing drum, but it may be carried by the address plate, another slot being provided therein for that purpose. In either case, the Salutation may very conveniently be a logotype, as but tions are, ordinarily used,- Dear Sir, Dear Madam, Gentlemen. Whether the Salutation is carried by the drum or the plate, the platen S5 is so positioned as to miss it when the envelop is printed.

It will be seen that my invention provides a very e'liicient machine by which the body of the letter with an address and the envelop may be printed ,to match, the envelop being delivered on the printed letter, and both imprints being effected by the same character of type through the same inking ribbon and by, the same kind of pressure. The machine may be used simply for printing envelope, being rotated back and forth through sufficient portions of opposite rotations which allow for the printing of the address and the replacement of the plate. During such movement the main idle by 43 into the depression 45%. On the other hand if it be desired to printqan address on the letter but no envelop, the envelop platen manently idle position by turning .the eccentric bushings in which its shaft is mounted. If no' address at all is to be printed, the address plate maybe oscillated to print the body of the letter. Or, for this latter character of work, the spool 52 may be disconnected from the spring barrel and mounted in the rotatable drum with the ribbon passing across the type, and the drum rotated continuously in the left-hand direction.

raving thus described my invention, WhatI claim is 2- n a machine of the character described, the combination with means for carrying a form for the body-of a letterand form, of two platens, means whereby one coiiperates with both .the body .and address and the other only while it is in the same position with relation to the body, whereby print addressed letters and corresponding '7 envelops.
